Extraordinary people - Iceman

In January this year, Wim Hof ran a half Marathon (21 km) above the polar circle in Finland. He wore only a pair of shorts and no shoes. The ground (snow) temperature was 35 below. In a few months time, he'll try something similar on Everest's north side. The expedition, led by Dutch Werner de Jong, will try to set a new world record as Wim attempts to climb parts of Everest wearing only shorts.

This is not your regular stunt. Wim already has 9 world records, and has trained hard for many years to withstand cold, much like some monks do in Tibet.

Wim can actually regulate his core heat to control the temperature of his skin. Something of a medical enigma, Wim is able to withstand cold that could kill or seriously injure other people.

On Everest, Wim will also put to use his free style climbing skills - which he once demonstrated hanging between 2 hot air balloons by his middle finger at an altitude of 1500 meters. Once back inside the basket, Wim finished by climbing to the top of the balloon.

One of Wim's world record attempts took him to the North Pole, where he held his breath for about 6 minutes and 20 seconds below the ice.
